javascript - 用于比较开始和结束日期的 jQuery 验证

Question

我有两个字段。一个用于 person_start_date，另一个用于 person_end_date。两者都有年、月、日三个单独的字段。我想验证人结束日期 > 人开始日期。提前致谢。

html.erb

<%= datetime_select :person_start_date %>


   <select id="person_start_date_1i" name="person[start_date(1i)]"> ... </select>
   <select id="person_start_date_2i" name="person[start_date(2i)]"> ... </select>
   <select id="person_start_date_3i" name="person[start_date(3i)]"> ... </select>

html.erb

<%= datetime_select :person_end_date %>


  <select id="person_end_date_1i" name="person[end_date(1i)]"> ... </select>
  <select id="person_end_date_2i" name="person[end_date(2i)]"> ... </select>
  <select id="person_end_date_3i" name="person[end_date(3i)]"> ... </select>

Answer 1

这里有一个建议:

var startDate = new Date(
    $('#person_start_date_1i').val(),
    $('#person_start_date_2i').val() - 1,
    $('#person_start_date_3i').val()
);
var endDate = new Date(
    $('#person_end_date_1i').val(),
    $('#person_end_date_2i').val() - 1,
    $('#person_end_date_3i').val()
);
if (endDate > startDate) {
    // do something
}
